Override default log location for JMeter when launching with Java (not command line)

Question

Is there an equivalent of the -j command-line option when launching JMeter using Java?

I'm running a series of test scripts that each need to have a custom log name - normally I'd just define each log location using -j, but in these cases they need to be launched through Java.

1. If you have possibility to amend the java code and invoke System.setProperty function :

   System.setProperty("jmeter.logfile", "/desired/path/to/jmeter.log)"
   

2. If you don't:

   • either pass the property via -D command line argument like:

     java -Djmeter.logfile=/desired/path/to/jmeter.log ....
     

   • or add the next line to system.properties file:

     jmeter.logfile=/desired/path/to/jmeter.log
